Abstract

PURPOSE:To improve the efficiency of a stop lapp without hindering a back field of view by shining a field of view selecting high polymer film, which is provided in a rear window of an automobile, in red color only at the time of lighting a light source provided in a rear tray, and while maintaining it transparent in ordinary. CONSTITUTION:A field of view selecting high polymer film 2 is attached to the predetermined position inside of a rear glass 3. A red color filter 4 and a light source 5 forming a light source part for radiating the red color beam toward the described film 2 are buried in the predetermined position of a rear tray 3. When the light source 5 is lighted with the operation of a brake, the light radiated from the light source 5 is passed through the red color filter 4 to become the red color beam, and is made to enter the described film 2. At this stage, the described film 2 has a characteristic that it is transparent within the predetermined angle and it is opaque at any angle except the predetermined angle. As a result, the described film 2 shines in red to be monitored with eyes 6A of a driver of a following automobile as lighting display of a stop lamp.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a high-mounted stop lamp installed in an automobile.

[Conventional technology]

Installing a high-mounted stop lamp near the rear window makes it easier for drivers of cars following to see the illuminated display, which is effective in preventing rear-end collisions. For this reason, for example, as shown in FIG. 3, the rear tray of an automobile 20 is selected as the installation location, and the high-mounted stop lamp 21 is installed so that its light-emitting display surface can be seen from outside the rear window 22.

(Problem to be solved by the invention) However, with the high-mounted stop lamp installed on the rear tray in this way, when looking backwards in the rear-view mirror, the high-mounted stop lamp 21 is reflected in the rear-view mirror, making it difficult to see the rear view. It becomes a hindrance.

An object of the present invention is to provide a high-mount stop lamp that can be installed on a rear tray without obstructing rear visibility.

[Means to solve the problem]

The present invention includes a viewing field selective polymer film disposed at a predetermined position of a rear window of an automobile, and a light source unit installed in a rear tray so as to irradiate a red light toward the viewing field selective polymer film. The field-selective polymer film glows red only when illuminated by the light from the light source.
It is usually a transparent film.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

Figures 1(A) and 1(B) show an embodiment of the present invention;
1 is a rear window glass, 2 is a field-selective polymer film pasted to a predetermined position on the inner surface of the rear glass 1, 3 is a 1-ray, 4 is a red filter, and 5 is a light source (for example, an incandescent light bulb).

The red filter 4 and the light source 5 constitute a light source section for directing red light toward the field selection polymer film 2, and these are placed at a predetermined position on the rear tray 3. l
I have set up.

The visual field selection polymer film 2 is transparent when viewed from a certain angle, and when the angle is above or below a certain angle, light rays are scattered.
It has the property of being opaque as if viewed through frosted glass, and at the angle shown in Figure 2 (A), the viewing field selection polymer film 29 becomes transparent, and at the angle shown in Figure 2 (B). Then it becomes opaque (light diffusion state).

Therefore, when the light source 5 turns on in conjunction with the brake operation as shown in FIG. 1(A), the light emitted from the light source 5 passes through the red filter 4 and becomes a red light beam,
1u2. This incident part shines red and is visible to the eyes 6A of the driver of the following vehicle as a lighting indicator of a stop lamp.

-= h, when the light source 5 is a dim light as shown in Fig. 1 (B), it is not visible to the eyes 6B of the driver of the car in question (viewed through the rearview mirror) and the eyes 6A of the driver of the following car. The visual field selective polymer film 2 is not visible 1, that is, the visual field selective polymer film 2 behaves as a transparent film for the driver of the vehicle concerned and the driver of the following vehicle, and does not obstruct rear visibility.

The field-of-view selection polymer film 2 may be sandwiched between the glasses 1 of 7 glasses 1 and placed in a 1\1 diagonal manner, or it may be shaped like letters or figures and made visible as a letter or figure display. good.

Further, in the above embodiment, the light source section is embedded in the rear 1 to ray 3, but it may be placed in the rear 1 to ray 3-L.

Furthermore, the light source part can be replaced with a red IEf) etc.
iJ Noh.

〔Effect of the invention〕

According to the present invention, as shown in FIG.
It consists of a field-selecting polymer film placed at a predetermined position on the window and a light source installed in the rear tray to irradiate red light onto the film, so that the field-selecting height is only set when the driver's line of sight is turned on. The molecular film glows red and is normally transparent, making it possible to install it on the rear millimeter without obstructing rearward visibility.
